Academic Coaching As A Transition Model For Graduating College Students With Disabilities
<p>The primary purpose of this study was to determine if there was a statistically significant difference in the bachelor’s degree graduation rates of three groups of undergraduate students at a regional, public university in Kentucky. The three groups consisted of those registered with disability …

Analyses and predictions of ultrasound interactions with model biomembrane systems via two-state transition model
… ultrasound interactions near to the lipid phase transition temperature. The enhanced ultrasound absorption spectra closely resemble single relaxation spectra, suggesting that the membrane constituents undergo a simple two-state transition. The temperature dependence of the relaxation frequency is …

A New State Transition Model for Forecasting-Aided State Estimation for the Grid of the Future
… levels. This dissertation proposes a new state transition model for power system forecasting-aided state estimation, which aims at capturing the increasing stochastic nature in the states of the grid of the future. The proposed state forecasting model is based on time-series modeling of filtered …

A scenario-based technique to analyze UML design class models
… proposed to rigorously analyze UML design class models that include operations specified using the Object Constraint Language (OCL). A UML design class model is analyzed against a given set of scenarios that describe desired or undesired behaviors. The technique can leverage existing class model …

Design and Analysis of Low Reynolds Number Marine Propellers with Computational Fluid Dynamics (CFD) Transition Modeling
… at low Reynolds numbers, where laminar-turbulent transition of the boundary layer can impact the distributions of pressure and shear stress on the blade surface. Marine propellers operating at low Reynolds numbers are subject to laminar-turbulent transition of the boundary layer, which impacts the …

Democratization in South Korea during 1979-1987
Most scholars who study the transition from authoritarian regimes to democratic ones use an actor-oriented approach, and assume four major actors participate in the negotiated transition. They explain the results of such transitions by analyzing the strategic interactions of these four major …

Modélisation de la transition solide-fluide dans les géomatériaux. Application aux glissements de terrain.
… our work concerns, in a general way, solid-fluid transition in geomaterials behavior and the development of a constitutive model describing both the solid phase, fluid phase, and the transition between the two. In this framework, we chose to carry out calculations with the FEMLIP numerical method …
